How to troubleshoot the low-pressure issue that your pressure washer brings in?

Do you lose your patience when you find out that your electric washer stalls when you started? Let’s now dive into all the possible troubleshooting steps wasting no time!

1. Nozzle connection

As you pulled the trigger of your cleaning gadget, found pressure issues? Did you check the nozzles?

An outlet with dirt clogged all around suppresses the flow of water and gives you no pressure as needed. You face the same in case of damaged or worn out nozzles.

So, we suggest you going through the following steps to check your outlet connection:

  • Firstly, detach it and go for deep cleansing to remove all kinds of grime and dirt. You can use any cleaning kit or simply needles for this.
  • Still, your pressure washer loses pressure after a few seconds? Then we would ask you to go for a new one at this point as it might be damaged.
  • You better give it a tight attachment.

2. Unloader issues

The unloader action may be one of the prime reasons that cause this problem. But why take the stress all by yourself. We’re here to help you manage it in a short time.

We’re aware of the troubles when the pressure washer shuts off when trigger is pulled. For this:

  • At first, detach the unloader from the device using a wrench and screwdriver.
  • We would advise you to inspect the O-ring or seal, valve setup, and pressure gun next.
  • Clean the piston using kerosene or alcohol.
  • Next, check the unloader disk or piston if it moves freely and controls the water flow.

Our final suggestion would be the change in your tool’s unloader.

3. Insufficient supply of water

How can you expect no chance of pressure issue when you are running short of adequate water supply? Well, were you thinking, how’s that?

The two main factors for uninterrupted water flow, such as PSI and GPM, are related to the washer machine’s high-pressure performance. Let’s see what the significance of these terms is and how to deal with it!

  • GPM indicates the exact number of water-filled gallons your washer can supply in a minute.
  • PSI is the pressure your washer applies to each one pound. You better learn in detail what PSI pressure washer to clean concrete and other surfaces.
  • Hence, they are vital to bringing out regular and large pressure levels.
  • Make sure your cleaning device matches the PSI and GPM you desire to have. Otherwise, trading it with a new one would sound the best.

4. Fixing valves

A pressure-based washer is decked with many large and small parts. Inlet valves and discharging valves are the most crucial of them. They target to give you a smooth water flow maintaining optimal pressure.

Fixing the valve is no big deal. All you need are:

  • Check out if the valves are clogged or not.
  • How can you expect it to give 100% cleansing when it’s not clean itself? If clogged, get your cleaning kit and clean!
  • You must look at the strainer size to get the desired water flow. Always use the perfect size.
  • Make sure you test the valve springs and, if needed, repair it using your tools.
  • But wait, is it damaged? Or the spring defective? Then the only choice left for you is changing it with a new one.

5. High-pressure hose 

Did you recently add a new hose on your unit to ensure high pressure? Yet your pressure washer stalls when trigger is pulled? Then you must have made some blunders while installing them.

Worried about your new expense? No, don’t. Follow the guidelines below:

  • Size in terms of width and diameter matters a lot in this case.
  • So you better check the diameter first before you install the hose.
  • Unsure about the hose size? Give a keen look at your user manual and dial!

7. Maintaining a suitable rate of water flow

Did you find all fine by now with nozzles and supply? Then it’s the flow rate of water that gives you room for doubts. It’s all because if your water path is not clear, what makes you think that you will get the same pressure you need to clean?

So for this, you need to follow:

  • Test the water flow rate at first, turning on the pump.
  • If you find an anomaly in the water supply pattern, check the water path.
  • Cleanse your cleaning tool!

Additional troubleshooting steps

  • Belts slippage: Correct your belt with a tight fastening to avoid slippage. Otherwise, it may result in low to no pressure on your device.
  • Inlet hose and strainer: While you are not checking, your washer can trap some dirt and cause pressure issues. So we advise you to clean them frequently!
